Ever since Demi Lovato announced last week that she was entering a treatment facility to deal with "emotional and physical issues," rumors have swirled about just what was happening in the Disney star's life that got her to that point.

"Demi Lovato is not in treatment for drug or alcohol addiction," says the rep. "As we have said since she entered treatment last week, Demi decided to seek help for emotional and physical issues she has battled throughout her life. She has taken this step in order to get her life in order."

Adds the rep, "While we know many are interested in Demi and her life, we do ask for a modicum of privacy during this difficult time."
